With the advent of Industry 4.0, industrial networks are becoming increasingly digitized.
But while this brings many gains in productivity, quality and efficiency, it introduces new — and never before considered — cybersecurity vulnerabilities.
Due to its critical nature, operational technology (OT) networks — digital networks on the production floor — require specific security tools beyond those used in IT networks themselves. Intrusion detection systems (IDS) are considered one of the most effective of these tools, as they passively monitor network traffic and don’t pose risks to ongoing operational processes.
To help counter growing threats and attacks, cybersecurity company Radiflow today announced a technology partnership with Cisco to provide IDS in Cisco-run OT facilities.
MetaBeat will bring together thought leaders to give guidance on how metaverse technology will transform the way all industries communicate and do business on October 4 in San Francisco, CA.
“The shortage of resources with OT security expertise is quite high and keeps growing,” said Ilan Barda, Radiflow‘s cofounder and CEO. “As such, it is important to use such integrations to reduce the need for manual work.”
OT facilities like Cisco’s are a growing attack surface
Barda described an “alarming” increase in cybersecurity attacks against OT facilities.
To this point, a Trend Micro survey of industrial cybersecurity in manufacturing, electric and oil and gas companies revealed that nine out of 10 organizations had production or energy supplies impacted by cyberattacks in the past 12 months. The average cost of such attacks was $2.8 million, and more than half (56%) of respondents said disruptions lasted four or more days.
Such disruptions have given rise to new and evolved security tools: According to a recent re …
